The research results were published in《Crystal Growth & Design》 in 2022.Formula: C13H11N3 The article conveys some information:

Pyridyl-substituted imidazoquinolines are highly fluorescent probes and are useful for the design of smart materials. A hitherto unknown pyridyl-imidazoquinazoline-coordinated two-dimensional (2D)-Cd(II)-MOF {[Cd₂(5-nip)₂(pdiq)₂(H₂O)₂(CH₃OH)]·H₂O}_n (CP 1), [H₂nip = 5-nitroisophthalic acid and pdiq = 6-(pyridin-4-yl)-5,6-dihydrobenzo[4,5]imidazo[1,2-c]quinazoline] was designed and structurally confirmed by single-crystal x-ray crystallog. The presence of C-H···π and π···π interactions in CP 1 makes it a three-dimensional (3D) supramol. structure. The excellent luminescent behavior of CP 1 is selectively quenched by trinitrophenol (TNP) even in the presence of potentially intrusive nitroarom. explosives (NAEs). A limit of detection (LOD) of 2.75 x 10^-7 M for TNP is achieved (3σ/m). In addition, the CP 1 displays elec. conductivity on an electronic device with the metal-semiconductor (MS) junction. Current vs. voltage (I-v plot) correlation reveals the substantial enhancement of elec. conductivity upon illumination (Λ: 1.12 x 10^-3 S m^-1 (dark), 6.33 x 10^-3 S m^-1 (light)) along with a decrease in energy barrier (Φ_B: 0.53 (dark), 0.42 (light)). The plots of log Vvs. log i show a non-ohmic feature at a higher voltage (log V ≥ 0) both in the dark and the light phase, which is the characteristic of a Schottky diode barrier (SDB).2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) were involved in the experimental procedure.

2-(1H-Benzo[d]imidazol-2-yl)aniline(cas:5805-39-0 Formula: C13H11N3) is a chemical reagent used in the synthesis of small molecule inhibitors targeting ubiquitin-like domains for treatments of diseases caused by the cellular accumulation of damaged proteins.

The article was appeared in 《Synthetic Metals》. They have made some progress in their research.Related Products of 65039-09-0 The article mentions the following:

Recently, an important focus of material research has been aimed at more sustainable smart materials with biodegradable, biocompatible properties such as those based on cellulose (Cell), made stimuli-responsive with the addition of multiwall carbon nanotubes (CNT). Formulated as fibers, such materials have potential applications in smart clothing and wearable’s in actuation or sensing function. In order to ensure maximum performance, an optimal driving voltage and regime must be chosen. In addition to the quant. effects, the actuation response also qual. and mechanistically changes, depending on the voltage range. The linear actuation measurements combined with cyclic voltammetry and square wave potential steps were performed in aqueous lithium bis(trifluoromethane)sulfonimide solution The Cell-CNT fiber actuation response properties were investigated at different potential ranges: 0.8-0.0 V, 0.8 V to – 0.3 V, 0.8 V to – 0.55 V and 0.65 V to – 0.6 V, observing a change in actuation direction between the ranges. Not just the potential range but also the driving frequency had an impact on the response, therefore, the selection of driving parameters is shown to be critical for controllable performance. To complete the study, the researchers used 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

COA of Formula: C6H11ClN2《Structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids》 was published in 2022. The authors were Huang, Liurong;Ding, Shuang;Chen, Tian;Wu, Ruike;Wang, Xinyu;Jia, Shifang, and the article was included in《Journal of Applied Polymer Science》. The author mentioned the following in the article:

This paper explores the structural and functional properties of collagen from tilapia scales pretreated by heat-assisted ionic liquids (ILs). Results show that the solubility of collagen was significantly influenced by the type and concentration of ILs. With the increase of IL concentration, a remarkable decrease in solubility of collagen was seen. Fluorescence spectra show that heat and IL pretreatments induced the exposure of chromophores. Changes in sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that subunits of collagen regenerated from most of the IL solvent systems were not destroyed. The functional properties of regenerated collagen were evaluated by gel strength, viscosity, water-binding capacity, and emulsifying capacity. Results show that all heat-assisted ILs pretreatments improved the gel strength and viscosity, and the highest gel strength and viscosity were both obtained in the collagen pretreated by heat-assisted [EMIM]Cl. Heat-assisted [BMIM]BF₄ pretreatment exhibited the lowest water-binding capacity. Heat-assisted [BDMIM]Cl pretreatment indicated superior effect on improving emulsifying capacity than other pretreatments due to its ability to break most of the hydrogen bonds in collagen mols., resulting in the formation of new re-aggregates with higher solubility and more hydrophobic groups. And 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) was used in the research process.

Due to the advantages of high temperature stability, low corrosion, and good heat transfer performance, potassium nitrate aqueous solution holds application potential in absorption systems. In order to further improve its absorption ability, ionic liquids (ILS) such as [Emim]Cl, [Emim]Ac, and [Emim]Br were selected as additives. In this paper, vapor pressures of four {KNO₃ + ILS + H₂O} ternary systems were measured by a dynamic b.p. method, including {KNO₃ + [Emim]Cl + H₂O}, {KNO₃ + [Emim]Ac + H₂O}, {KNO₃ + [Emim]NO₃ + H₂O}, and {KNO₃ + [Emim]Br + H₂O}. Molar ratios between KNO₃ and ILs were 1:1 for these systems, and the total absorbent mass fractions were in the range of 0.20 to 0.70. Exptl. data were regressed by Antoine-type equations, and the average absolute relative deviations (AARD%) between the exptl. and calculated values were no more than 0.78%, which showed good consistency of these experiments Vapor-liquid equilibrium behavior of these different ionic liquid ternary systems were compared and [Emim]Ac showed best performance in reducing vapor pressure at relatively higher mass fractions.

Ren, Fei;Wang, Jinwei;Yu, Jinglin;Zhong, Cheng;Xie, Fengwei;Wang, Shujun published 《Green synthesis of acetylated maize starch in different imidazolium carboxylate and choline carboxylate ionic liquids》. The research results were published in《Carbohydrate Polymers》 in 2022.Recommanded Product: 65039-09-0 The article conveys some information:

This work demonstrates that acetylated maize starches (AMS) with varied degree of substitution (DS, 0.26-2.63) was synthesized in ionic liquids (ILs) (imidazolium chloride, imidazolium carboxylate and choline carboxylate) at 85°C without catalyst. The DS of AMS and reaction efficiency increased with decreasing alkyl chain length of cations or anions, while decreased as the choline cation replaced the imidazolium cation and the chloride anion replaced the acetate anion. The AMS synthesized in imidazolium-based ILs exhibited much higher hydrophobicity and thermal stability than the native starch. Rheol. properties of ILs and ATR-FTIR anal. of acetic anhydride/ILs mixtures indicated that a shorter alkyl side chain or the combination of an imidazolium cation and an acetate anion gave ILs lower viscosities and weaker interactions between acetic anhydride mols., which favored the acetylation of starch. These findings provide insights into the design of green processes to modify starch and the application of acetylated starch. The experimental procedure involved many compounds, such as 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) .

They have made some progress in their research.Application In Synthesis of 1-Ethyl-3-methyl-1H-imidazol-3-ium chloride The article mentions the following:

In this study, liquid-liquid equilibrium data of an aqueous two-phase system (ATPS) composed of alcs. (ethanol, 1-propanol, or 2-propanol) and small-mol. organic compound (sodium citrate, sodium tartrate, sucrose, maltose, and lactose) was extensively investigated at 298.1 K ± 0.1 K. The binodal curves were summarized through the empirical nonlinear equations with the lowest standard deviation. The contents of alcs. and organic salts in ATPS were accurately determined by gas chromatog. and UV spectrophotometer. The phase-forming abilities of alcs. were ranked in the following order, 1-propanol > 2-propanol > ethanol, resp. The ATPS composed of saccharides was difficult to form two phases due to the high viscosity. The salting-out abilities of sodium citrate (C₆H₅Na₃O₇) were better than sodium tartrate. 1-propanol/ C₆H₅Na₃O₇ATPS had larger biphase areas, it was further applied to concentrate various ionic liquids including [C₂mim]BF₄, [C₄mim]BF₄, [C₄mim]Cl and [C₈mim]Cl. The results showed that alc./organic salt ATPS had a better extraction rate to imidazole-type ionic liquids Ionic liquids were mainly distributed in the top phase (alc.-rich phase).

The present work focuses on the development of a new electrochem. platform based on CoMn2O4-rGO/1-ethyl-3-methylimidazolium chloride modified carbon paste electrode (CoMn2O4-rGO/IL/CPE) for electrochem. determination of pethidine in the presence of biol. species. For the first time, the electrooxidation mechanism of pethidine in presences of morphine and olanzapine is investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) technologies. The as-synthesized CoMn2O4-rGO nanocomposites are characterized by physicochem. measurements such as X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), Field emission SEM (FE-SEM), and Fourier transform IR (FT-IR). The obtained results illustrated synergistic interactions between rGO and CoMn2O4 structures. Also, to investigate the electrode charge-transfer resistances, electrochem. features of the resulting nanocomposites are studied via electrochem. impedance spectroscopy (EIS) anal. Based on the result, three segmented linear ranges are observed over the range 0.08-900μM and detection limit of 0.024μM. Over the 10.0-40.0μM ranges of pethidine in phosphate buffer solution (PBS-pH 7.0), suitable diffusion coefficient of 5.67 x 10-7 cm2 s-1 is evaluated by chronoamperometry technique (CHA). Finally, the CoMn2O4-rGO/IL/CPE with high sensitivity, selectivity and repeatability is successfully used for determination of pethidine in real sample and drug formulation.1-Ethyl-3-methyl-1H-imidazol-3-ium chloride (cas: 65039-09-0) were involved in the experimental procedure.
